Oil leak on a '92 Geo Tracker. Installed an O Ring, but still leaking. Any suggestions?


O-ring where? The drain plug? Distributor shaft? Or do you mean oil seal?
Geo oil drain plug specifies a compressible copper ring washer I think? Need to clean the surfaces well, and torque to spec. My own plug's seal is not perfect, but only a drop here and there usually. Autozone or NAPA can supply you a new plug and washer if needed.

Oil leak front engine timing chan


1995 Tracker would have a timing BELT. Normal oil leak points (in order) on a Suzuki G16 engine are the distributor base (rear of motor), valve cover (top of motor), front main seal (behind lower timing belt cog) cam seal (behind the upper timing belt cog) and rear main seal. (behind the flywheel). I'd suspect the front main seal or cam seal. I use foot power to help find oil leaks.

Is the front engine seal related to the time chain tensioner seal got a link behide the timeing belt


Don't quiet understand your question...but here's some insight.

The chain is under the valve cover/s ( 1.8t and some 2.8 V6.) and drives 2 or 4 cam shafts.

If it is the VR6 engine then the chain is in the front of the engine.

1.8t has seals on at cam sensor at rear of head and seals at front for crank and cam. To install it needs belt removed for front seals. 2.0 gas engine same except no rear cam seals.

All oil seals are now Teflon and a new instal procedure must be followed. Briefly : Installed dry...allowed to sit 4 hours before engine started.

Post again if this does not answer your question. We need year and model to give you a definitive answer.

1988-1993 ford festiva leaking oil around the crank pulley... could the oil be coming out of timing chain seal... are could it be a the seal on the crank shaft.. if so would i need to removle the engine to...


This sounds like the crank seal, the engine doesnt have to be removed, in order to get to seal is like replacing the ttiming belt, and once in the timing belt i would replace the crank and cam seals, also do the timing belt, and maybe the waterpump, you will need to remove the crank pulley and then the timing covers then align timing marks for timing belt before ou remove it, with timing belt off the crank pulley then slides off the crankshaft and the seal is behind it, the cam shaft gear unbolts and the seal is behind the gear, once the gears are off then you will be able to remove the seals from the engine,heres a few diagrams to help. good luck and i hope this is helpful,60d826b.gifca916fa.gifcb2cb5a.gif

How to change time chain on a 3.3 v6 dodge caravan, easy way to look at timeing chain, so i can tell if it is bad


This design has no tensioner. Check the sprockets for wear on the tips--especially the crank sprocket. With the cover off, turn the crankshaft with a socket and see how close the chain comes to slipping backward on the sprocket. There are complete replacement procedures at AutoZone.com, which I will try to paste in below.

3.3L and 3.8L Engines

See Figure 18



0900c15280215ddb.jpg enlarge_icon.gifenlarge_tooltip.gif Fig. Fig. 18: Timing mark alignment-3.3L and 3.8L engines
  1. If possible, position the engine so that the No. 1 piston is at TDC on the compression stroke. Disconnect the negative battery cable. Drain the coolant.
  2. Remove the timing chain case cover. For more information, refer to the Front Timing Cover and Seal procedure, earlier in this section.
  3. Remove the camshaft gear attaching cup washer and remove the timing chain with both gears attached. Remove the timing chain snubber.

To install:
  1. Assemble the timing chain and gears.
  2. Turn the crankshaft and camshaft to line up with the key way locations of the gears.
  3. Slide both gears over their respective shafts and use a straight edge to confirm alignment.
  4. Install the cup washer and camshaft bolt. Tighten the bolt to 35 ft. lbs. (47 Nm).
  5. Check camshaft end-play. The specification with a new plate is 0.002-0.006 in. (0.051-0.052mm) and 0.002-0.010 in. (0.51-0.254mm) with a used plate. Replace the thrust plate if not within specifications.
  6. Install the timing chain snubber.
  7. Thoroughly clean and dry the gasket mating surfaces.
  8. Install new O-rings to the block.
  9. Remove the crankshaft oil seal from the cover. The seal must be removed from the cover when installing to ensure proper oil pump engagement.
  10. Using a new gasket, install the chain case cover to the engine.
  11. Make certain that the oil pump is engaged onto the crankshaft before proceeding, or severe engine damage will result. Install the attaching bolts and tighten to 20 ft. lbs. (27 Nm).
  12. Use tool C-4992, or equivalent, to install the crankshaft oil seal. Install the crankshaft pulley using a 5.9 in. suitable bolt and thrust bearing and washer plate L-4524, or equivalent. Make sure the pulley bottoms out on the crankshaft seal diameter. Install the bolt and tighten to 40 ft. lbs. (54 Nm).
  13. Install all other parts removed during the chain case cover removal procedure and fill the engine with oil.
  14. Connect the negative battery cable, road test the vehicle and check for leaks.

I am replacing the water pump of my 1995 3.0 v6 infinity (same as altima) but my son removed the chain with out marking it, now I need to set the timing. How do I do this? There's marking on the valve...


This should be the same engine as the Maxima. If that is the case, there is no reason to remove timing chain or get it out of time. The pump is driven by the timing chain, but is not "in time".

The pump is under its own cover. The chain tensioner is under its own cover. The pump is removed after the tension is released on the chain, the tensioner pinned in its retracted position to take tension off chain, and the crank is rotated about 20 degrees counter clockwise to slacken the chain at the pump sprocket without coming off the cam sprockets. Then, the pump is remove by removing its mounting bolts and then screwing in three long M8 bolts as jack bolts into 3 holes (carefully and evenly) to jack out pump. The pump is sealed from the engine case by two o-rings that must be replaced. I think the pump mount bolts are sealed with silicone when replaced. I would get a Haynes or other reliable manual.

If you truly have to reset or check timing, definitely get a book.
